Abstract
An arch-shaped corrugated chamber having corrugation peaks and valleys, with reinforcing ribs provided on the corrugation peaks. The ribs extend upwardly from a chamber base to a rib upper end, and have an arch-shaped cross-section with an outer surface extending outwardly from a corrugation peak and a fin extending inwardly from the corrugation peak, and optionally, a rib line provided on the rib outer surface on the rib arch-shaped cross-section. A channel formed by the inner surface of the rib is sized to receive a corresponding rib of a second chamber so that multiple similar chambers with ribs may be stacked together.
Claims21
A chamber, comprising:
- a cellular plastic foam arch-shaped corrugated chamber having a plurality of corrugation peaks and a plurality of corrugation valleys distributed along a length of the chamber, the corrugation peaks and corrugation valleys extending transverse to a lengthwise axis of the chamber, the chamber having a top portion and two side portions, with a base at a lower end of each side portion;
- a rib provided on a plurality of the plurality of corrugation peaks, each rib having an outer surface extending outwardly from a corrugation peak and a fin extending inwardly, wherein each rib has an outwardly extending arch-shaped cross-section with the fin extending inwardly from the rib arch-shaped cross-section, the rib arch-shaped cross-section having a depth and the fin having a depth, and wherein the fin depth is less than the depth of the rib arch-shaped cross-section, and wherein each rib extends upwardly from one of the bases to a rib upper end, and the rib arch-shaped cross-section decreases in size from the one of the bases to the rib upper end;
- the rib having a depth, the rib depth and the fin depth tapering from a greater depth adjacent to the one of the bases to a lesser depth above the one of the bases;
- and
- whereby the rib and the fins define a channel sized to receive a corresponding rib of a second chamber, the channel having a depth varying from a maximum depth adjacent the one of the bases to a minimum depth adjacent a location above the one of the bases.

A chamber, comprising:
- a cellular plastic foam arch-shaped corrugated chamber having a plurality of corrugation peaks and a plurality of corrugation valleys distributed along a length of the chamber, the corrugation peaks and valleys having a thickness, the corrugation peaks and corrugation valleys extending transverse to a lengthwise axis of the chamber, the chamber having a top portion and two side portions, with a base at a lower end of each side portion;
- a rib provided on a plurality of the plurality of corrugation peaks, each rib having an arch-shaped cross-section extending outwardly from a corrugation peak and having an outer wall, each rib further having a fin extending inwardly from the rib arch-shaped cross-section and a rib line on a rib outer surface on the rib arch-shaped cross-section;
- each rib extending upwardly from one of the bases to a rib upper end;
- the rib arch-shaped cross-section having a wall thickness and a depth, and the fin having a depth;
- the fin depth being greater than the arch-shaped cross-section wall thickness at a location adjacent to the one of the bases and less than the rib arch-shaped cross-section depth;
- the rib arch-shaped cross-section depth and the fin depth tapering from a greater depth adjacent to the one of the bases to a lesser depth above the one of the bases;
- and
- whereby the rib arch-shaped cross-section and the fin define a channel sized to receive a corresponding rib of a second chamber, the channel having a depth varying from a maximum depth adjacent the one of the bases to a minimum depth adjacent a location above the one of the bases.
